DOUBLE ROTARY FORCE-PUMP.

To (ti/Z 1072,0111, it may concern-.-

Be it known that I, J ULIUs R; NORTON, a citizen of the United States,and a resident of San Antonio, in the county of Bexar and State ofTexas, have invented a new and Improved Double Rotary Force-Pump, of.which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved doublerotary force-pump which is simple and durable in construction, not

liable to easily get out of order, very effective in operation, andarranged to render the pump positive in its action and to prevent anyloss of power.

Theinvention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all thefigures.

Figure 1 is a plan view of the improvement. Fig. 2 is a side elevationof the same, one of the cylinders being shown in section on the line 2 2of Fig. 1. Fig. 3 is a cross-section of the improvement on the line 3 3of Fig. 1. Fig. A is a side elevation of one of the pistons and itspiston-heads, the shaft of the piston being shown in section. Fig. 5 isa cross-section of the same on the line 5 5 of Fig. 4. Fig. 6 isa planview of the same. Fig. 7 is a cross-section of a modified form of theimprovement. Fig. 8 is a side elevation of one of the pistons, the shaftof the piston being shown in section. Fig. 9 is a cross-section of oneof the pistons, and Fig. 10 is an inner face view of one of thecylinder-heads.

The cylinders A and A of the force-pump are preferably formed in asingle casting having a base A for fastening the pump to a suitablefoundation, and the said cylinders are arranged parallel and spacedapart by an integral partition A The base A is made hollow to form aninlet A, connected by a pipe or other means with the liquid to bepumped, and the said inlet A has two branches A A opening into thecylinders A and A at the lower end of the partition A On the top of thecylinders A and A is formed an integral outlet A, having branches A andA opening into the cylinders A and A at the upper end of the partition Aas plainly shown in Fig. 3. In the cylinder-heads B B for the cylindersare journaled the shafts O C, arranged eccentrically in the cylinders Aand A and connected with each other at their outer ends by gear-wheels Dand D,so that the shafts O and U rotate in unison. One of the shafts (asshown the shaft C) is provided with a pulley E, connected by a belt withother machinery for imparting a rotary motion to the said shaft O, whichby the gear-wheels D and D rotates the other shaft, O, in unison withthe shaft O. a

On the shafts O and O within the cylinders A and A are secured thecylindrical bodies F and F of pistons having heads F F diametricallyslidable in the said piston-bodies F and F, the piston-head F being setin quarter position relative to the piston-head F, as plainly indicatedin Fig. 3. Each of the piston-heads F 01 F is made in sections F and Fpressed apart by springs F, held on guide-pins F, on which the sectionsF and are slidably mounted, the said guide-pins and their springsextending through suitable openings in the shaft 0 or C.

By the arrangement described the outer ends of the sections F and F ofthe piston-heads F and F are always held in firm contact with the innerperipheral face of the corresponding cylinder A or A, so that leakage ofliquid from one side of the piston-head section to the other isprevented. The cylindrical piston-bodies F and F are in peripheral orrolling contact with the partition A on opposite sides thereof, asplainly indicated in Fig. 3, and hence when the pistons are rotated inthe cylinders A and A and in the directions of the arrows a then theliquid is drawn in through the inlet A and by the branches A A into thecylinders A A, in which the piston-heads F F carry the liquid around andforce the same out through the branches A A into the outlet A, connectedby a pipe or other means with asuitable place of discharge.

By setting the piston-heads of the two pistons in quarter positionrelatively one to the other it is evident that a continuous pumping ofWater takes place, and at the same time the pistons counterbalance eachother to insure a uniform running of the pump.

In order to prevent priming, a false head G is arranged in one end ofeach cylinder A and A to abut against one end of the correspondingpiston, and this false head G can be readily adjusted by suitable screwsH, as plainly indicated in Fig. 2.

In the modified form illustrated in Figs. 7, 8, 9, and 10 the springsfor the piston-heads are dispensed with, and in this case the sections Fand F of the piston-head are wholly independent one of the other, butslid able radially in the piston-bodies F and F. The ends of thesections F and F" are provided with trunnions F fitting grooves I,formed in the adjacent cylinder-heads, so that when the pistons arerotated, as previously explained, then the trunnions F in following thegrooves I cause the piston-heads to slide radially in their bearings inthe piston-bodies F and F. Otherwise the construction of the pump is thesame as above described relatively to Figs. 1 to 6, and hence furtherdetail description of the pump shown in Fig. 7 is notdeeined necessary.

From the. foregoing it will be seen that the pump is very simple anddurable in construction, is composed of comparatively few parts, notliable to easily get out of order, and by the arrangement set forth acontinuous stream is sucked up and forced out by the action of the pump.

1 do not limit myself to the detail construction shown, as the same maybe varied Without deviation from the spirit of my invention.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1.
